deleting when nothing is there
Hey I know how to use grep to eliminate a row when nothing there is a character that I dont want. But I encountered a problem where there is nothing there. Heres my example: Code:
Nam1 Nam2 Year Nam3 Month So for Nam1 there is nothing in the second column so I want to delete it... so anything that has nothing in the second column should be removed. Code:
Nam2 Year Nam3 Month I tried grep but what do i grep for? or is there a faster solution?  thanks |

assuming you want to eliminate rows that have less than three columns: Code:
awk 'NF>2' inputfile> outputfile change the > 2 part to accomodate your needs. NF means number of columns/fields & > 2 is greater than two. |
